Configuring ATM Router Module Interfaces
This chapter describes steps required to configure the ATM router module on the Catalyst8540 MSR,
Catalyst 8510 MSR, and LightStream 1010 ATM switch routers, and the enhanced ATM router module
for the Catalyst 8540 MSR. The ATM router module allows you to integrate Layer 3 switching w ith
ATM switching on the same ATM switch router.
Note This chapter provides advanced configuration instructions for the Catalyst8540 MSR,
Catalyst 8510MSR, and LightStream 1010 ATM switch routers. For complete descriptions of the
commands mentioned in this chapter, refer to the ATMSwitch Router Command Reference publication.
For hardware installation and cabling instructions, refer to the ATMand Layer 3 Module Installation
Guide.
Note The LightStream 1010 system software image does not include support for the ATM router module or
Layer 3 features. You can download the Catalyst 8510 MSR image to a LightStream 1010 ATM switch
router with a multiservice ATM switch processor installed.
